What does the Bible teach about works and salvation?

In the sermon, it is pointed out that many people mistakenly believe their good works can earn them favor with God. However, true salvation comes through faith in Christ alone. As seen in Galatians, those who emphasize works to justify themselves are operating under the false assumption that their actions can affect their standing with God. The preacher emphasizes that our confidence should be placed solely in Christ's finished work, illustrating that genuine faith produces good works as a response to salvation, rather than a prerequisite for it.
